cds-question@unistra.fropen-star-clustersccd-photometryvisible-astronomyh-beta-photometrymedium-band-photometryb-starsWe present CCD uvby{beta} photometry for stars in the nuclei of the young double cluster {h} and {chi} Persei. We find that the reddening is highly variable through the {h} Per nucleus, increasing from west to east, with values ranging from E(b-y)=0.328+/-0.022 in the western part to E(b-y)=0.465+/-0.025 in the south-east. Towards {chi} Persei the reddening is fairly constant, with E(b-y)=0.398+/-0.025. Both clusters share a common distance modulus of 11.7+/-0.1mag, and an age of logt=7.10+/-0.05 years.2002A&A...394..479Chttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/394/479CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toV/27 : Proper Motions and UBV Photometry in h+chi Per (Muminov 1980)J/A+A/394/47 : uvby{beta} photometry of h and chi Per (Capilla+, 2002)J/AJ/122/248 : h and chi Per UBVI,H{alpha} photometry (Keller+, 2001)J/ApJ/576/880 : CCD UBV photometry of h and {chi} Per (Slesnick+, 2002)J/PASP/114/233 : h and {chi} Per memberships (Uribe+, 2002)J/A+AS/119/271 : Be stars uvby{beta} photometry (Fabregat+, 1996)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/394/479https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/394/479http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/394/479https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/394/479https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/394/479http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/394/479GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/A+A/394/479/table6 (Coordinates and photometry for stars in h Per)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/394/479/table6?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/394/479/table6?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/394/479/table6?GETtext/xml+votable180.050000true34.655541757.13591670.005555555555555556Cone search capability for table J/A+A/394/479/table7 (Coordinates and photometry for stars in chi Per)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/394/479/table7?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/394/479/table7?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/394/479/table7?GETtext/xml+votable180.050000true35.368541757.17080560.0055555555555555566/3256-3257https://cdsarc.cds.unistra.fr/viz-bin/moc/J/A+A/394/479?format=asciiOpticaldefaultJ/A+A/394/479/table6Coordinates and photometry for stars in h Perm1m1 indexmagphot.colorfloatc1c1 indexmagphot.colorfloatrecnoRecord number assigned by the VizieR team.
